Why do red giant stars expand?
Because they begin to run out of fuel
How long does a hot air balloon stay in the air?
It all depends on the amount of fuel you have, most hot air balloons carry 1-2 fuel tanks. On average a hot air balloon burns 25 Gallons of propane an hour, and average fuel tank is a 10 Gallon fuel tank, sometimes 15 Gallons, meaning roughly 45 minutes to an 60 minutes, sometimes its a cool day, you'll require less fuel for more heat, it will last up to an 90 minutes. However, larger balloons carry more fuel, and can stay in the air longer.
What happen to a sun-like star after it has used up all the fuel in its core?
Towards the end of its life, a star with a size similar to ours will expand to a red giant star as the core contracts and heats up and the hydrogen fuel supply is consumed. It will eventually lose the outer layers and all that will be left is a core, a white dwarf reminant that will slowly cool over millions of years.
What are the large cool stars that are not in the main sequence?
Large cool stars that are not in the main sequence are known as "red giants" or "red supergiants." These stars have exhausted the hydrogen fuel in their cores, causing their inner regions to contract while the outer layers expand. As a result, they become larger and cooler than when they were on the main sequence. Red giants are typically found in the later stages of stellar evolution, after they have exhausted their core hydrogen and started fusing helium in a shell around the core. They are often reddish in colordue to their lower surface temperature compared to main sequence stars. Red supergiants are even more massive and larger than red giants, representing the final stages of the life cycle of massive stars before they undergo supernova explosions or other dramatic events.
What are two types of stars that can form when a star runs out of fuel?
When a Star runs out of fuel, it will expand into what is known as a "Red Giant". Massive stars will become "Red Supergiants". This phase will last until the star exhausts its remaining fuel. At this point, the pressure of the nuclear reaction is not strong enough to equalize the force of gravity and the star will collapse. Go to related link to read more about Stars... ;)
What is an eight letter word that the definition is an old star of average size that has begun to expand and cool as its fuel has begun to run out?
red giant
How is the red-giant formed?
A red giant forms when a star runs out of hydrogen fuel at its core and starts fusing hydrogen in a shell around the core the core. This causes the star to expand and cool.
How are pwcs fuel tanks designed for safety?
They are designed to leave space for fuel to expand.
Where is my Fuel pump located in a 97 Tahoe?
The fuel pump is located in the fuel tank to keep the fuel cool. That way the fuel is cool pumping to the engine so it doesn't vaporize.
Do stars expand in size?
Stars expand in size to become red giants, when they start running low on Hydrogen fuel.
What safety feature what designed into pwc fuel tanks?
The safety feature that was designed into PWC fuel tanks was to leave space for the fuel to expand.
Why do red giant stars expand?
Because they begin to run out of fuel
Why does a 1995 eugeot 106dt runs unevenly when hot?
the fuel injectors expand when hot and will flood the system change out the fuel injectors
Where is the fuel pump on a 1990 Toyota Supra?
The Pump Is Located In The Tank. Fuel Keeps It Cool.
How much does diesel fuel expand in volume in relation to ambient temperature?
one third
What is average cost to clean fuel injectors?
The average cost to clean fuel injectors is about $150. Fuel injectors are used to deliver fuel into an internal combustible engine.
Does fuel flow to keep fuel pump cool?
Yes and some are in tank for the same reason they are immersed in it
